Yes, your 7372 has both a 2.4G radio and a 5G radio, and will advertise SSIDs on
one 2.4G channel and one 5G channel. If you don't specify your SSID is only for
one band, the AP would advertise it on both 2.4G and 5G radios.

But yes, it is normal to see all of an AP's 2.4G or 5G SSIDs on the same 2.4G or
5G channel.
